    • The invention comprises an animal having a presurgical substantially normal gastrointestinal tract, which gastrointestinal tract has been surgically modified such that postsurgically there is a reduction of the volume of the stomach of the gastrointestinal tract, a reduction in the digestive area of the gastrointestinal tract, a reduction in the co-mingling of food with gastric, biliary and pancreatic juices, a reduction in the presurgical gastric output of the peptide ghrelin, a reduction in the threshold for satiety, a permanent reduction in presurgical weight, and an induction of a condition of malabsorption. The surgically-altered animal may be adapted for use as an animal model in a method wherein the biological mechanisms underlying obesity and its reduction may be investigated; and, in which the molecular biological effects of surgical intervention for obesity may be investigated; and, in which the efficacy of noninvasive alternatives to surgical intervention for obesity may be investigated.
    • 本发明包括具有术前基本上正常的胃肠道的动物,其胃肠道已被外科手术改造,使得胃肠道胃的体积减少,胃肠道消化区减少, 食物与胃,胆汁和胰汁的共混减少,肽生长素释放肽的胃外输出量减少,饱腹感降低,手术重量的持续降低,以及诱导的 吸收不良 手术改变的动物可以适用于以下方法中的动物模型:其中可以研究潜在的肥胖及其减少的生物学机制; 并且其中可以研究用于肥胖的外科手术干预的分子生物学效应; 并且可以研究非侵入性替代物对肥胖的外科手术干预的功效。
